Anotace:
Trametes versicolor (L.) Lloyd is a wood-decaying medicinal fungus belonging to the division Basidiomycota. Mycelial mass of T. versicolor IBK 353 was obtained after submerged cultivation on a liquid medium with waste bread (breadcrumb) and complex glucose-yeast medium with beer wort. The chemical composition and nutritional value of mycelia depended on the medium for cultivation. The ash, crude protein, and crude fat contents were 3.8, 1.6, and 1.4 higher correspondingly in mycelium cultivated on complex glucose-yeast medium with beer wort than on breadcrumb. The protein in T. versicolor IBK 353 mycelia contained 34-37 % of essential amino acids, and lipids comprised 60-76 % of unsaturated fatty acids. T. versicolor IBK 353 dry mycelia were enriched in folates, and 100 g contained a daily recommended dose of riboflavin and 81-100% of niacin. Mycelia of T. versicolor grown on two investigated media as a source of biologically active substances may serve to create functional foods and dietary substances.
